摘　　要：无线mesh网络(WMN,wireless mesh networks)中采用多接口和多信道能有效地增加网络容量。分析多接口多信道WMN架构及其信道分配问题,重点指出其特殊性和难点。对信道分配研究模型协议模型和图论模型进行总结。阐述在信道分配过程中要着重考虑的问题。提出多接口多信道WMN中信道分配问题面临的挑战。The use ofmulti-radio and multi-channel in wireless mesh networks （WMN） can improve network capacity effectively. The paper introduces the network architecture of wireless mesh network with multi-radio and multi-channel, and the corresponding channel assignment problem. It summarizes several important channel assignment models, including protocol model and physical model, which are helpful for research, discusses the key issues of channel assignment, and proposes challenges of channel assignment for WMN with multi-radio and multi-channel.
